It seems like once you manually edit a Spring WebFlow config file a certain way, then the visual editor no longer works.

As I am spending more time in the XML editor modifying WebFlow config files, I am continuously getting this dialog box popping up:

Problem Occurred
‘Refresh Property Sheet’ has encountered a problem.
An internal error has occurred.
java.lang.NullPointerException

I have to restart the IDE in order to get it to stop. Its only a matter of time before it starts up again.
